EMPI-IREY J. RUBOTTOM, OF FELTON, CALIFORNIA.

PLOW.

SPECIFICATION forming part of Letters Patent No. 759,474, dated May 10, 1904.

Application filed August 18, 1902. Serial No. 120,147. (No model.)

To all 'whom t party concern:

Be it known that I, EMPHREY J. RUBoTToM, a citizep of the United States, residing at Felton, in the county of Santa Cruz and State of California, have invented certain new and useful Improvements in Plows; and I do hereby declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention is, generally speaking, an improvement in plows; but to be more specilic it is an improvement in reversiblemoldboard plows.

The plow possesses all the requisites of strength and durability and is especially simple in construction and eflicient in operation.

My plow is so arranged that the share by which the bottom of the furrow is eut remains permanently stationary relative to the frame or stock, while the moldboard by which the furrow-slice is turned over is capable of being quickly and readily reversed and locked in a set position to turn the furrow-slice either to the right or left.

In carrying out my invention I have aimed at structural simplicity and economy, and the many objects and advantages of the same will, it is thought, be readily seen by examining the accompanying drawings in conjunction with the following specification.

In the drawings, Figure l is a perspective View of the complete plow. Fig. 2 is an enlarged elevation of the rear portion of the plow with one of the handles broken away. Fig. 3 is a rear elevation of the moldboard and connecting parts. Fig. 4 is a perspective view of the pivotal forward extremity ofthe moldboard, and Fig. 5 is a section on'thc line .fr m of Fig. 2.

Referring now to the above views by letter, A represents the beam of the plow and is built of two halves a and L which are bolted together and straddle the post B and stand* ards C. Rigidly secured to the lower extremity of the post B is the share D, to the rear extremity of which is hooked the end e of the horizontal runner E, the latter being rigidly secured to the standards C.

rIhe moldboard F is bent over at its forward end and is pivotally attached to the neck of the runner E, While its rear extremity is upheld and pivoted to the rear end of runner E by means of the Y-shaped brace Gr. The chain H, which is adjustable in the forked plate I, hoclld the moldboard firmly against the standar From the description so far gone into it will be readily seen that should it be desired to reverse the moldboard all that is necessary to do is to release the chain H from plate I and swing it into the position shown in dotted lines in Fig'. 3, then secure chain H and the plow is ready for operation.

In order to adjust the dip of the share D, I have provided the adjustable rod J which is pivoted to the upper end of post B and engages with plate I by means of suitable set and lock nuts f.

The draft-rod M is connected directly with the post B and is adjustable at its forward end in a slot in the cross-piece N.

It will be readily seen from the foregoing description that I have provided a very simple and effective plow capable of performing all the functions usually asked of this class of device.

I am aware that changes in the form and proportion of parts of the devices herein shown and described as an embodiment of my invention can be made without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes, substitutions, and alterations as fairly fall within the scope of my invention.

Vhat I claim, and desire to secure by Letters Patent, is

A plow provided with a suitable beam, a post adjustably secured to said beam, a share rigidly secured at the foot of said post, a runner secured to the plow-beam at thevrear of said share, connected to the latter by a flexible connection, and a reversible moldboard pivotally mounted on the runner in front and secured to the runner at the rear by a swinging connection, substantially as specified.

In testimony whereof I aliix my signature in presence of two witnesses.

EMPHREY J. RUBO'ITOM.
